Kubica's team criticism 'good'

(GMM) Peter Sauber, the BMW-Sauber team founder, consultant and minor shareholder, has backed Robert Kubica's recent criticism of the German outfit's rate of development in 2008.

Kubica, the on-form Polish race driver, won the recent Canadian grand prix but then declared that Swiss based BMW-Sauber must work harder to close the gap to F1's top teams Ferrari and McLaren.

"Robert wants more. That is exactly why we took him under contract two and a half years ago," Sauber wrote in his latest column for the Swiss newspaper Blick.

"He was once asked what three things he would take with him to a deserted island, and he answered: a racing car, tires and gas. This sums him up very well," he added.

"He is focused totally. His whole life is arranged for success. Mentally he is terribly strong, demanding an awful lot of himself and those around him.

"That is the wood from which champions are carved," Sauber said.

Peter Sauber said Kubica, 23, was justified to feel disappointed after the Magny-Cours race, where he finished just fifth.

"Robert has more ambitious goals than that," he admitted, "which is pleasing and a good thing."
